DESCRIPTION
The DAC8551 is a small, low-power, voltage output,
16-bit
digital-to-analog
converter
monotonic, provides good linearity, and minimizes
undesired
code-to-code
DAC8551 uses a versatile 3-wire serial interface that
operates at clock rates to 30 MHz and is compatible
with standard SPI, QSPI, Microwire, and digital
signal processor (DSP) interfaces.

The DAC8551 requires an external reference voltage
to set its output range. The DAC8551 incorporates a
power-on-reset circuit that ensures the DAC output
powers up at 0 V and remains there until a valid write
takes place to the device. The DAC8551 contains a

The low-power consumption of this device in normal
operation makes it ideally suited for portable battery-
operated equipment. The power consumption is
1.00 mW at 5 V, reducing to 1 μW in power-down
mode.
The DAC8551 is available in an MSOP-8 package.
